ok, i'm all for it.

you just wrote it yourself:

that option and the column names are the deactivated settings i was referring
to, for write.csv() and write.csv2(). they are not all on the same tab -- i
tried to make the dialog as similar to the import plugin as possible, but
there are quite some differences.

sure, this is only an idea. but let me explain how it came to this: firstly, i
was thinking about people who want to learn R; there should also appear an
explaining comment above the write.csv() call explaining that the commented
options cannot be changed here (btw, if you try, write.csv() throws a warning
saying the same). secondly, the commented options show the value that they're
set to internally; for instance, "col.names" depends on the setting of
@aaron: what do you think would be most useful? the generated code currently
# some options can't be changed with write.csv()
# they have been commented out to show the values they are set to
the stripped alternative would be:
the R code currently also includes all defaults. if we want to strip it down
to the absolutely necessary arguments only, it would result in just this:

i actually included that snipped first, but it added another full tab and had
a checkbox for "converting strings" which i didn't find the best wording here.
so i copied the dropdown menu -- and added the checked "(default)" option,
since write.table() defaults to 'fileEncoding=""'.
having something to embed would be great, but i still didn't really get how to
write an embeddable plugin ;-)
